I thought that was Pinball Dreams from the thumbnail, I loved that game! I played it to death on the Amiga. And Pinball Fantasies too, but I don't recognise the name Pinball Illusions.
We knew that the game was going to be cracked, given that we ourselves did some cracking and distributing of cracked copies. So was not really a big thing, but we did put in some crack detections that altered some of the scoring and ball physics in later games, that was never fixed by the crackers so they played worse than if you owned the original game.
That's quite funny.
